| Abstract: | Selection for the photocatalytic degradation of p-bromophenol were investigated .The mechanism of nano-TiO 2 catalysis degrading organic compounds in waster water and some effects on photocatalysis degradation rate including light intensity,TiO 2 concentration,temperature,pH value of waster water and impurities ect,were also studied.Accordingly,it is necessary to optimize those effects to improve the photocatalysis degradation rate. |
